It is true that the Friendship Boats are not running now, but we don't know whether they will be running in October. We also don't know what time the Skyliner will be closing then.
You can't take a bus to a closed park, and the Friendship boats usually close an hour after park closing.
If the Skyliner is running at the time you finish dinner, it would be the best way to Pop. If it isn't, and the parks have closed, your only no-cost option is a bus to DS, and then a bus to the resort. But that can take quite a while, so you might want to consider Uber or Lyft.
